As expected, this works fine: foo :: Fractional a => a foo = undefined -- datum bar :: Num a => a -> a bar a = undefined -- function baz :: Fractional a => a baz = bar foo -- applicat...

I am learning some polymorphism. The wiki page for rust addresses trait is a method to achieve ad hoc polymorphism, and the page for ad hoc polymorphism says function overloading is an example of a...

I have a pluggable runtime type checker that supports parametric but no ad-hoc polymorphism, because there is no compiling step and type information are erased as soon as the type checker is deacti...

I'm wondering if there are general ways to convert between ad-hoc polymorphic functions and parametric polymorphic ones. In other words, given an ad-hoc polymorphic function, how to implement its p...

I am having a problem understanding the different types of polymorphism, specifically in regards to OCaml. I understand that polymorphism allows for multiple types in OCaml denoted as 'a, but I do ...

What is the precise promise/guarantee the Haskell language provides with respect to referential transparency? At least the Haskell report does not mention this notion. Consider the expression (7^...

This code doesn't compile: let f = fun x y -> x <<< y // bit shift let g = fun x y -> x <<< y [<EntryPoint>] let main _ = printfn "%d" <| f 1 10 printfn "%d" &l...
